FIG. 46 FRUIT AND 

 LEAF BUDS OF 



PEACH 



A, end of two-year 

 and beginning of one- 

 year wood. Buds 

 largely in threes. The 

 outside ones are fruit 

 buds the ones between 

 leaf buds. B, is con- 

 tinuation of another 

 part of the shoot an- 

 other third part. Such 

 growths must be cut 

 back severely both to 

 reduce the numbzr of 

 fruits and to prevent 

 the undue extens'on 

 of the branches from 

 the terminal buds, 

 more particularly. The 

 whole one -year part of 

 the branch in this case 

 is 30 inches long. It 

 is cut in A at 8 inches 

 and in B at 10.

Japanese plums suggest the apricot in bloom-bearing 

 habit axillary buds on spurs and also on vigorous young 

 wood; in this latter case, like peach bloom buds, in 

 couples, with a branch bud between. 1 Hiring the dormant 

 season the .recognition of plum blossom buds is often ex- 

 ceedingly difficult, though in some varieties it is easy.
